Question

The arsenius sulphide sol has negative charge the maximum coagulating power for precipitating it is of -

• A. $0.1\left(N\right)Zn(N{O}_3{)}_2$
• B. $0.1\left(N\right)N{a}_{3}P{O}_4$
• C. $0.1\left(N\right)ZnS{O}_4$
• D. $0.1\left(N\right)AlC{l}_3$

Answer 1

The correct option is D $0.1\left(N\right)AlC{l}_3$

More the valency of cation greater will be its coagulating power as per hardy schulze rule.
